Numerical analysis of the non-stationary thermal state of the tool in the combined casting and extrusion of aluminum alloy

The results of a numerical analysis unsteady heat transfer in the “metal-mold-environment” system during continuous combined casting and extrusion an aluminum alloy installation with horizontal carousel mold are presented. engineering zones characterized by different intensity between melt surface have been determined. A quantitative assessment influence rate heating crystallizer on temperature-time characteristics period transient thermal process is given. It shown that increase productivity reduces duration when starting from cold state until it reaches stationary regime. dependence time at which regime rotation speed wheel has obtained.
